I did the same, delaying my order from October hoping that there might be the soft refresh model Y. I end up placing the order end of November. I lost $375 referral bonus and now getting Sep 2023 build instead of the newer build.Just got assign VIN, I think I've been assigned a GC car (due for delivery from 23 Jan- 14 Feb). Although I probably don't care all that much, out of principle I as starting to wonder whether I should just forfeit the $400, and reorder in order to obtain a 2024 build. We did actually wait unti late December to order in the hope that we might get a 2024 build (but would have been fine if that didn't work out). To then end up with a Sep -23. build does p' me off a little bit.
Then the question is ... when would you have to reorder to ensure you weren't allocated another GC car!!
I understand from others here that Tesla say there is nothing you can do to get reassigned a different VIN. Does anyone know what happens if you don't pick it up during the designated delivery period. I thought I heard at some point you go to the back of the line and reassigned a new vehicle.
